Purpose
With the proliferation of terrorist/extremist websites on the World Wide Web, it has become progressively more crucial to detect and analyze the content on these websites. Accordingly, the volume of previous research focused on identifying the techniques and activities of terrorist/extremist groups, as revealed by their sites on the so-called dark web, has also grown.
Design/methodology/approach
This study presents a review of the techniques used to detect and process the content of terrorist/extremist sites on the dark web. Forty of the most relevant data sources were examined, and various techniques were identified among them.
Findings
Based on this review, it was found that methods of feature selection and feature extraction can be used as topic modeling with content analysis and text clustering.
Originality/value
At the end of the review, present the current state-of-the- art and certain open issues associated with Arabic dark Web content analysis.

Research surrounding radicalization to and use of violence among extremist and terror groups has expanded over the last decade. There are still fundamental questions that must be addressed, particularly regarding the role of the Internet in radicalisation and recruitment as well as general technological skill within extremist groups. Few studies have considered this issue, especially among Far Right groups which have been identified as one of the top threats to public safety within the United States. This exploratory study addresses these issues using a qualitative analysis of a sample of threads from a technology-specific subforum of a widely used web forum in the white nationalist and white power movement. The findings demonstrate that the process of information sharing is distinct from that of more sophisticated deviant and criminal communities on-line, as users readily answer basic technological questions rather than discuss offensive attack techniques. The implications of this study for future research are examined in depth.

The ISD Germany study on the extreme right-wing use of Telegram serves as a complementary text to the “Escape routes” report. In it, the research team examined links to other platforms, which were shared on the controversial messenger service and were disseminated in the channels of right-wing extremists, right-wing radicals and conspiracy ideologues in the German-speaking world. The main scope of this research was on smaller platforms that do not fall under the deletion obligation of the NetzDG. Links to larger platforms such as YouTube, Facebook and Twitter were also analysed, given that the collected data set contained almost twice as many links to these platforms than to those not fully covered by the NetzDG.

For this report, the ISD research team collected 659,110 messages from 238 public channels from the extreme right, radical right, Reichsbürger:innen and conspiracy ideology spectrum between 1 January and 12 September 2021. From these messages, 371,988 links were extracted, leading to 8,252 domains. The ISD Germany researchers examined domains that were shared more than 15 times and identified social networks and platforms.
